C2-Acylated indoles have been synthesized in good yields through palladium-catalyzed dehydrogenative coupling of N -pyrimidine-protected indoles using aldehydes as the source of acyl reagent and tert -butyl hydroperoxide as the oxidant. 2-Indole carboxylates can be synthesized when aldehydes are substituted by ethyl glyoxylate.
